Tasmania, Australia
9.5 x 6 x 2.6 CM (cabinet)

Spring 2020

Slender bright red-orange crystals of Crocoite rise above a contrasting white Gibbsite matrix. A choice specimen with most crystals in good shape, terminated and a few with hoppered form. Minimal damage as is almost inevitable with this sort of fine needles, but most is not visible by naked eye. From a 2014 pocket, this has the color and luster that is most desired, the needles are up to 1.6 CM.

Crocoite and Vauquelinite -Type Locality
stock #0654-JM-4287
Berezovsk Mine, Ekaterinburg, Sverdlovskaya Oblast, Middle Urals
Urals Region, Russia
8.8 x 5.6 x 4.3 CM (cabinet)
price: $880
Late Summer 2018

Very rich, fine old classic specimen (with 4 prior labels) that is well crystalized. Excellent color contrast with the bright red Crocoite and green Vauquelinite, This seems to be a late 18th or early 19th century specimen, (what may be a date of 1895 is on one label but it may also be a collection number). The discovery of Crocoite at this locality dates back to 1763 and it has been renamed many times over the years. The style of specimen and the association of good Vauquelinite is typical of the vintage pieces. Ex John Marshall collection, his collection card and a previous label indicate it sold for $12.00 in 1956, a vast sum for any mineral at that time. The August 2016 Mineralogical record article on this locality offer a wealth of information and several other good specimen photos. This specimen is far beyond average quality with only very minor bruising, most crystals are intact and are well exposed on the matrix. Virtually impossible to find this quality now on the market, better in person too.
